> So there is no need to scan the databases then. "No need" is a bit too strong. It's true that, generally, there is no need to run an on-demand scanner regularly - but many people like to do that; perhaps in order to get a confirmed feeling that their machine is clean (even if that feeling is, in some cases, ill-founded).
In general, we do on-demand scanning after booting from a known-clean environment (e.g., a bootable CD-ROM), in order to ensure that a system is really clean. Anything less (i.e., running the scanner with the virus potentially active) is unreliable. It's not easy to translate this concept to the PalmOS environment - perhaps, if the scanner was in ROM and scanning after a hard reset... Also, the algorithms for on-demand scanning are sometimes used during what should be considered on-access scanning. For instance, one of the possible virus entry points is the insertion of a memory card. When this event occurs (i.e., on-access), the scanner should start scanning the card - but it would do it just the same way as an on-demand scanner when the latter is told to scan the card on demand. > What if I just bought your antivirus and want to make sure that > there is no virus on my palm? Mine will be free, so you won't have to buy it. :-) But, jokes aside, the proper way to do it is like this: after a hard reset, you should install the virus protection first and only then you should start installing everything else. This will ensure that the protection is started in a virus-free environment and it should prevent any known viruses from entering after that point. (Modulo the cases when a virus could have burned itself in the Flash ROM - on those devices on which this is possible.)
